Research Overview

My research focuses on microbiology education. I have led or been on several teams working on developing and using concept inventories to determine students' mastery of microbiology and immunology. My current research involves helping students increase their performance on multiple-choice exams.


  • Microbiology 303: Biology of Microorganisms
  • Microbiology 304: Biology of Microorganisms Laboratory
  • Microbiology 527: Physiology of Microorganisms Laboratory
  • Microbiology 551: Physiological Diversity of Procaryotes Laboratory


The courses in the major are taught on a rotational basis, and I teach Microbiology 303, Microbiology 304, Microbiology 527 and Microbiology 551 in various years. I am also active in the scholarship of teaching: participating in seminars, presentations, and publications. Other responsibilities include:

• Co-director of the Masters Degree program in Bacteriology
• Author of Through the Microscope an online microbiology textbook, Why Microbes Matter  a book for the general public, and Virtual Microbiology 
• Serving on the Editorial Board of the Journal of Microbiology and Biology Education.
